"American Psycho" is a novel by Bret Easton Ellis, published in 1991. The story is told in the first person by Patrick Bateman, a serial killer and Manhattan businessman. Alison Kelly of 'The Observer' notes that while "some countries so potentially deem it disturbing that it can only be sold shrink-wrapped", "critics rave about it" and "academics revel in its transgressive and postmodern qualities".

A film adaptation starring Christian Bale as Bateman was released in 2000 to generally favorable reviews. In 2008, it was confirmed that producers David Johnson and Jesse Singer were developing a musical adaptation of the novel to appear on Broadway. The musical premiered at the Almeida Theatre, London in December 2013.

Author Bret Easton Ellis initially imagined a disillusioned but nonviolent protagonist. After a dinner with friends who worked on Wall Street, he decided to make him a serial killer. Patrick Bateman's idolization of Donald Trump is based on his friends' respect for and envy of the mogul.

Donald John Trump (born June 14, 1946) is the 45th president of the United States. Before entering politics, he was a businessman and television personality. He took charge of his family's real-estate business in 1971, renamed it 'The Trump Organization', and expanded it from Queens and Brooklyn into Manhattan. The company built or renovated skyscrapers, hotels, casinos, and golf courses.
